Schwannomas are well capsulated, benign, and slowly growing tumors which originate from Schwann cells of peripheral nerve sheath. The incidence of schwannomanas in the axillary region is not common. This rarity causes misdiagnosis at the radiological evaluation. In this case we present the imaging and histopathological findings of a cystic schwannoma located in the axillary fossa of a 47-year-o...

INTRODUCTION The use of ultrasound in regional anesthesia allows reducing the dose of local anesthetic used for peripheral nerve block. The present study was performed to determine the minimum effective concentration (MEC90) of bupivacaine for axillary brachial plexus block (ABPB). METHODS Patients undergoing hand surgery were recruited. To estimate the MEC90, a sequential up-down biased coin...

variations in the origin of axillary artery branches are common. but, distinctly abnormal course of its posterior circumflex humeral branch is rare. we are reporting a case of posterior circumflex humeral artery (pcha) originating from the axillary artery, passing through lower triangular space to reach the scapular region where it accompanied the axillary nerve and posterior circumflex humeral...

The effect of adding clonidine to local anesthetics for nerve or plexus blocks remains unclear. The authors searched for randomized placebo-controlled trials testing the impact of adding clonidine to local anesthetics for peripheral single-injection nerve or plexus blocks in adults undergoing any surgery (except eye) without general anesthesia. Twenty trials (1,054 patients, 573 received clonid...

UNLABELLED Conceição DB, Helayel PE, Oliveira Filho GR - A Comparative Study between Ultrasound- and Neurostimulation-Guided Axillary Brachial Plexus Block. BACKGROUND AND OBJECTIVES The use of ultrasound in Regional Blocks is increasingly more frequent. However, very few studies comparing ultrasound and neurostimulation have been conducted. The objective of this study was to compare neurosti...

Axillary nerve injury is a risk of the deltopectoral approach to the proximal humerus. The anterior motor branch is potentially vulnerable during subdeltoid dissection. Insertion of the pectoralis major tendon is an easily identifiable landmark on the humerus. This anatomical study explored whether the superior aspect of the pectoralis major tendon is a useful landmark for localizing the anteri...

MATERIALS AND METHODS: A systematic review was performed using the PubMED, SCOPUS, and Cochrane databases in order to identify all cases of isolated, posttraumatic axillary nerve injuries in patients 18 years or older. Patients who underwent axillary nerve reconstruction were included and categorized by technique: graft or transfer. Demographics were recorded, including age, time to operation, ...
